Cover Latching Mechanism

1. A cover latching mechanism, comprising: a base member comprising an elastic hook; and a cover member for assembly with the base member, a button assembly assembled with the cover member, comprising: a button member comprising a positioning arm and a sleeve portion and further defining a hooking hole above the sleeve portion, the elastic hook detachably latched into the hooking hole, the positioning arm secured to the cover member, the button member further comprising a pressing portion having a first surface and a second surface opposite to the first surface, the cover member defining a cutout accommodating the pressing portion therein; and an elastic restoring member rotatably received in the sleeve portion and latched with the cover member, the cover member comprising two protrusions at two sides of the cutout, each of the two protrusions defining a latching slot, the restoring member latched into the two latching slots; wherein the button assembly is configured for being pressed so that the restoring member deforms inwardly inside the cover member to release the elastic hook from the hooking hole, thereby the cover member can be removed away from the base member.

2. The cover latching mechanism as claimed in claim 1 , wherein the first surface has an elastic hooking portion formed thereon, the hooking hole defined through the elastic hooking portion.

3. The cover latching mechanism as claimed in claim 1 , wherein the sleeve portion defines an axial through shaft hole.

4. The cover latching mechanism as claimed in claim 1 , wherein the button member comprises two L-shaped bent portions, the bent portions arranged on the edges of the pressing portion.

5. The cover latching mechanism as claimed in claim 1 , wherein the cover member comprises a positioning block, the positioning block comprises a positioning post, the positioning arm defines a positioning hole fixing the positioning post therein.

6. The cover latching mechanism as claimed in claim 5 , wherein the positioning arm comprises an elastic arm portion and a positioning portion, the arm portion connected to the first surface, the positioning portion connected to the arm portion, the positioning hole defined through the positioning portion.

7. The cover latching mechanism as claimed in claim 1 , wherein the base member comprises a notch, the elastic hook protruded from the bottom of the notch.

8. A cover latching mechanism, comprising: a base member comprising an elastic hook; and a cover member for detachable assembly to the base member, a button assembly fixed to the cover member and movable relative to the cover member to latch to or release from the elastic hook, comprising: a button member comprising a positioning arm and a sleeve portion and further defining a hooking hole above the sleeve portion, the elastic hook engaging into the hooking hole so that the elastic hook latching the button assembly with the base member, the positioning arm configured for securing the button assembly to the cover member, the button member further comprising a pressing portion having a first surface and a second surface opposite to the first surface, the cover member defining a cutout accommodating the pressing portion therein; and a restoring member configured to be deformed when the button assembly pressed, so that the elastic hook is released from the hooking hole, the cover member comprising two protrusions at two sides of the cutout, each of the two protrusions defining a latching slot, the restoring member latched into the two latching slots.

9. The cover latching mechanism as claimed in claim 8 , wherein the first surface has an elastic hooking portion formed thereon, the hooking hole defined through the elastic hooking portion.

10. The cover latching mechanism as claimed in claim 8 , wherein the sleeve portion defines an axial through shaft hole.

11. The cover latching mechanism as claimed in claim 8 , wherein the button member comprises two L-shaped bent portions, the bent portions arranged on the edges of the pressing portion.

12. The cover latching mechanism as claimed in claim 8 , wherein the cover member comprises a positioning block, the positioning block comprises a positioning post, the positioning arm defines a positioning hole fixing the positioning post therein.

13. The cover latching mechanism as claimed in claim 12 , wherein the positioning arm comprises an elastic arm portion and a positioning portion, the arm portion connected to the first surface, the positioning portion connected to the arm portion, the positioning hole defined through the positioning portion.

14. The cover latching mechanism as claimed in claim 8 , wherein the base member comprises a notch, the elastic hook protruded from the bottom of the notch.
